Transition-Metal-Free Ring-Opening Silylation of Indoles and Benzofurans with (Diphenyl-tert-butylsilyl)lithium

A practical method is presented for ring opening various indoles and benzofurans with concomitant stereoselective silylation using readily generated (diphenyl-tert-butylsilyl)lithium to afford ortho-beta-silylvinylanilines or -phenols. Dearomatization of the heteroarene core proceeds in the absence of any transition-metal catalyst through addition of a silyl anion and a subsequent stereoselective beta-elimination. DFT calculations provide insight into the mechanism. Functionalizing C?X bond cleavage of heteroarenes is rare and generally requires transition-metal catalysts.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 24410-59-1 is helpful to your research. 24410-59-1

Synthesis and phosphodiesterase 5 inhibitory activity of novel phenyl ring modified sildenafil analogues

New sildenafil analogues containing an ether ring fused into the phenyl moiety, 6a-d and 7a-d, were efficiently synthesized from the readily available starting materials, 1a-d and 2, in five steps. Ab initio calculations indicated that introduction of a cyclic ether to the phenyl group might enhance the co-planarity of the molecule. The torsional angles were calculated to be 2-3 for the 5-membered cyclic ether derivatives, 6a, 6c, 7a, and 7c, and 12-16 for the 6-membered ones, 6b, 6d, 7b, and 7d. On the other hand, sildenafil showed the least co-planarity with the torsional angle of 23 compared with the target compounds, 6a-d and 7a-d. in the enzyme assay, however, the in vitro PDE 5 inhibitory activity was found out to be inversely related to the degree of co-planarity. In other words, the least planar sildenafil showed the highest actiivty, and the most planar 5-membered cyclic ether derivatives were least active by 100-200-fold compared with sildenafil. Our study clearly demonstrated that the open chain 2′-alkoxy group of the phenyl ring, although less effective for inducing the co-planarity, seemed to act as a much better lipophilic requirement than the cyclic alkoxy moiety.

Synthesis of 2,2-functionalized benzo[1,3]dioxoles

Highly functionalized catechol ketals exhibiting either a tert-butyl moiety or a spiro center in position 2 are synthesized by ketalization and functionalized in a sequence of subsequent transformations. By a specific ketalization protocol catechol ketals of enolizable beta-keto esters can be prepared. With the succeeding steps these compounds incorporate moieties, which are not compatible and accessible by direct ketalization of catechol.

Gas-Phase Substituent Effects in Stabilized Benzylic Carbocations. Basicities of Benzaldehydes, Acetophenones, and Methyl Benzoates in the Gas Phase

The gas-phase basicities of a series of aromatic carbonyl compounds (ArCOR; R=OMe, Me, H) were measured based on the proton-transfer equilibrium method using a pulsed ICR mass spectrometer. The effects of ring-substituents on the gas-phase basicities were analyzed in terms of the Yukawa-Tsuno equation. It was shown that the resonance demand parameter (r+) decreases significantly from 1.06 for the benzaldehyde to 0.50 for the methyl benzoate in increasing order of the electron-donating ability of the R group directly linked to the carbonyl carbon. This indicates that the pi-charge formed in the conjugate acid ion is competitively delocalized into an aryl group and an R group. In contrast, the p value is nearly constant at -11 (in kcal mol-1 per sigma= unit) in all series. Most importantly, it was found that the r+ value in the gas phase is in agreement with that for the basicities in aqueous solution, whereas the p value is significantly reduced in aqueous solution. This fact led us to the conclusion that the solvation of a cation reduces the central charge so as to lower the response to substituent perturbation, essentially without changing the nature of the intramolecular charge-delocalization.

Design, synthesis, and evaluation of inhibitors for severe acute respiratory syndrome 3C-like protease based on phthalhydrazide ketones or heteroaromatic esters

The 3C-like protease (3CLpro), which controls the severe acute respiratory syndrome (SARS) coronavirus replication, has been identified as a potential target for drug design in the treatment of SARS. A series of tetrapeptide phthalhydrazide ketones, pyridinyl esters, and their analogs have been designed, synthesized, and evaluated as potential SARS 3CLpro inhibitors. Some pyridinyl esters are identified as very potent inhibitors, with IC50 values in the nanomolar range (50-65 nM). Electrospray mass spectrometry indicates a mechanism involving acylation of the active site cysteine thiol for this class of inhibitors.

Syntheses of aromatic substituted 6?-thiothalidomides

A resurgence of interest in thalidomide has occurred as a consequence of its diverse immunomodulatory and anticancer actions, which has fuelled interest in synthetic analogues with higher potencies or less undesirable side effect profiles. Several novel aromatic substituted 6?-thiothalidomides were synthesized whose synthetic route and strategy were developed on the basis of an analysis of reaction mechanisms. The regioselectivity of mono-thionation of aromatic substituted thalidomides with Lawesson’s reagent is described, and the chemoselectivity of hydrogenation between the nitro group and 6?-thiocarbonyl group is discussed. Full characterization of eight substituted 6?-thiothalidomides is reported. Georg Thieme Verlag Stuttgart.

N-Heterocyclic carbene-catalyzed deaminative cross-coupling of aldehydes with Katritzky pyridinium salts

By employing an N-heterocyclic carbene (NHC) catalyst, we developed a versatile catalytic system that enables deaminative cross-coupling reactions of aldehydes with redox-active pyridinium salts. Katritzky pyridinium salts behave as single-electron oxidants capable of generating alkyl radicals enabled by the redox properties of the enolate form of Breslow intermediates. The resultant alkyl radical undergoes efficient recombination with the NHC-bound aldehyde-derived carbonyl carbon radical for the formation of a C-C bond. The mild and transition metal-free reaction conditions tolerate a broad range of functional groups, and its utility has been further demonstrated by the modification of a series of peptide feedstocks and application to the three-component dicarbofunctionalization of olefins.

Development of Allosteric Hydrazide-Containing Class i Histone Deacetylase Inhibitors for Use in Acute Myeloid Leukemia

One of the biggest hurdles yet to be overcome for the continued improvement of histone deacetylase (HDAC) inhibitors is finding alternative motifs equipotent to the classic and ubiquitously used hydroxamic acid. The N-hydroxyl group of this motif is highly subject to sulfation/glucoronidation-based inactivation in humans; compounds containing this motif require much higher dosing in clinic to achieve therapeutic concentrations. With the goal of developing a second generation of HDAC inhibitors lacking this hydroxamate, we designed a series of potent and selective class I HDAC inhibitors using a hydrazide motif. These inhibitors are impervious to glucuronidation and demonstrate allosteric inhibition. In vitro and ex vivo characterization of our lead analogues’ efficacy, selectivity, and toxicity profiles demonstrate that they possess low nanomolar activity against models of acute myeloid leukemia (AML) and are at least 100-fold more selective for AML than solid immortalized cells such as HEK293 or human peripheral blood mononuclear cells.
